Whalen's first interest in Eastern religions centered on Vedanta. Upon release from the army in 1946, he visited the Vedanta Society in Portland, but did not pursue this very far, because of the expense of attending their countryside ashram. Tibetan Buddhism also attracted him, but he found it "unnecessarily complicated." In 1952, Gary Snyder lent him books on Zen by D. T. Suzuki. With Snyder, Whalen attended a study group at the Jōdo Shinshū Buddhist Church in Berkeley.[4] Ultimately, Zen became his chosen path.[5]
